In a scatterplot, a dot represents a single data point. With several data points graphed, a visual distribution of the data can be seen. … The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger theRead More →

In order to create a scatter plot, we need to select two columns from a data table, one for each dimension of the plot. Each row of the table will become a single dot in the plot with position according to the column values. How do you name a scatter?Read More →

A Scatter (XY) Plot has points that show the relationship between two sets of data. In this example, each dot shows one person’s weight versus their height. What are the 3 types of scatter graphs? Graphs can either have positive correlation, negative correlation or no correlation. Positive correlation means asRead More →

A scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables. What data does scatter plots show? A scatter plot is a type ofRead More →

Due to the finite size of the focal spot, when the object is further away from the detector, the edges in the image of the object get blurred (Penumbra). The total blur (degradation) in the final image is a combination of detector and focal spot blurring. What are the effectsRead More →

Titling the Graph The proper form for a graph title is “y-axis variable vs. x-axis variable.” For example, if you were comparing the the amount of fertilizer to how much a plant grew, the amount of fertilizer would be the independent, or x-axis variable and the growth would be theRead More →

There are three types of correlation: positive, negative, and none (no correlation). Positive Correlation: as one variable increases so does the other. How can you tell if a scatter plot is positive or negative? We often see patterns or relationships in scatterplots. When the y variable tends to increase asRead More →
